It's a Role-Playing Game ... (OK that would only make people roll their eyes.)
"Role-playing" has a very specific definition in this case and playing just any role doesn't count cause that practically breaks the idea of an RPG ...
Role-playing in the case of RPGs would most likely mean being able to "assume multiple distinct roles that have their own specific purpose and skills" ...
A game with a class system that have differing purposes and abilities would be classified as an RPG. I believe this is the ORIGINAL definition of an RPG when it was defined as such for tabletop RPGs ...
